Board Components & Interfaces
User LEDs (D9 Through D16)
The board provides eight user-defined LEDs. A logic 0 driven to an LED
turns it off; a logic 1 driven to an LED turns it on.
Table 2–15 lists the schematic signal name and the corresponding
Stratix II GX device’s pin number.
Configuration DIP Switch (S6)
The configuration DIP switch is used to set up specific board functions,
such as FPGA bootstrap settings, JTAG chain bypassing, or configuration
setup. In the open position, the selected signal is driven to logic 0. In the
closed position, the selected signal is driven to a logic 1.
